Actually, since so much of the driving public is totally ignorant of other features of their cars, I doubt that most people would even be aware that their new car has stability control if they did not have to opt for it.
Think about it:
A huge percentage of the public does not know how to react when ABS kicks in. When the pedal begins its rapid vibration, their reaction is to back off on the brakes–and that is either because they don’t know that they have ABS or they are too ignorant to know how to utilize it. And then of course, we have people who pump their brake pedals and wonder why the ABS never kicks in on slippery surfaces.
As we see almost daily in this forum, something as relatively simple as the oil pressure warning light is a mystery to a huge number of drivers. After they wind up destroying their engine, they come to this forum and belatedly find out that their car ran out of oil even though the oil pressure warning light did not come on until the point where their engine had already sustained damage from poor lubrication.
Or–how about the folks who ask how to activate or to deactivate the overdrive gear on their transmission?
There are also the people who don’t know about the presence of child-proof locks on the back doors of their car, and who are puzzled because they suddenly can’t open the doors from the inside of the car.
Then, we have the folks who state that their car has a V-4 engine.
Heck, there are lots of folks who don’t even know how to spell the make and model of the car that they are driving!
You are giving all too much credit to the typically automotively-dumb American motorist. Most will never be aware that their car has a stability control system, and as a result will not make a conscious decision to drive recklessly. A-holes have always driven recklessly, and they will continue to drive recklessly, but with the inclusion of this life-saving feature, perhaps they will kill a few less innocent people in the process.
And, then we have the fact that stability control has actually existed on cars for at least 10 years–beginning first with just a few high-end models, and subsequently being extended year by year to lower-priced models as either standard equipment or at least as an option.
By now, there are–quite literally–tens of thousands of car on the roads daily with stability control. But–where is the evidence that drivers have had more accidents as a result of this feature?
The press, which is always looking for lurid tales to tell, has never–to my knowledge–run any coverage of “spectacular crashes caused by stability control”. Trust me–if there was even a scintilla of evidence that people had died as a result of stability control, the media would be flogging that allegation non-stop. Can you produce any evidence to the contrary?
So, no–I can’t imagine the spectacular crashes that will result when the margin provided by stability control is exceeded.
